description:
*.makevars.mk doesn't exist until after ${WRKDIR} is created, which
doesn't happen until after the package is extracted.  Prior to
extraction, cache the variables named in MAKEVARS using MAKEFLAGS
instead.  This avoids invoking each expensive computation up to four
times before it gets cached.  For packages that include lots of
buildlink3.mk files, this saves a lot of CPU time.
